CONTROLLING nnvron.

Patented July 9, 1918.

Application filed October 23, 1914. Serial N 0. 868,153.

To all whom it may concern:

Beit known that I, NEWMAN H. HOLLAND,

a subject of the King of Great Britain, and

a resident of Vest Orange, in the county of Essex and State of NewJersey, have in vented certain new and useful Improvements inControlling Devices, of which the following is a description. I

My invention relates to controlling devices and. especially tocontrolling devices for buslness or other phonographs,be1ng :1n

some aspects an improvement-on the invention described and claimed inPatent No. 1,106,443 granted August 11, 1914, to Nelson C. Durand andentitled controlling devices.

In the construction disclosed in the patent to Durand, the soundconveyer of the phonograph has applied thereto a device constituting ahandle, which is provided with a member movable with respect thereto foreffecting the starting and stopping of the phonograph mechanism. Thismember is normally biased to a position for effecting the stopping ofthe phonograph mechanism, and, in order to effect the starting of thelat.- ter, is moved from such position by the application of pressurethereto by the hand of the operator. It is necessary for the operator tomaintain the pressure on this member during the entire time it isdesired to continuously operate the phonograph mechanism, and when thistime is of considerable duration, as is frequently the case, themaintenance of this pressure becomes tiresome to the operator. Moreover,there is an inclination onthe part of some'operators, after applying tothe movable member the pressure necessary to effect the starting of thephonograph mechanism, to immediately remove this pressure, whereupon thesaid member willatonce return to its normal position and thereby effect.the stopping of the phonograph mechanismat a time when it is intendedthe same should be operating. I

The principal object of my invention is to provide a constructionwherein these objectionable features will be obviated. In conformitywith this object, I provide a' controlling device of the type abovedescribed with simple and improved means whereby when the member foreifecting the starting and stopping of the phonograph mechanism has beenmoved by the application of pressure thereto, to the position foreffecting the starting of the phonograph mechanism,

it will be automatically locked in such posit1on to prevent the stoppingof the phonograph mechanism after the removal of such dle forthe soundconv eyer of the phonograph.

Other objects and features of my invention reside in the details ofconstruction and combinations of elements hereinafter more fullydescribed and claimed.

In order that my invention may be more clearly understood, attention isdirected to the accompanying drawing, forming a part of thisspecification, in which the same reference characters are used todesignate corresponding parts throughout and in which- Figure 1 is aperspective view, partly broken away, of a phonographwith my inventionapplied thereto; I v

Fig. 2 is an enlarged longitudinal sectional view, partly in elevation,of the device provided with the movable member for efiecting thestarting and stopping of the phonograph mechanism and the improvedlocking means cooperating with such member, the parts being shown inposition for efiecting the stop ping of the phonograph mechanism; and aFig. 3 is an enlarged part sectional view of the outer end portion ofthe device asv ing mechanism through a clutch comprising ashiftableclutclrmember 4, movement of which in opposite directions serves torespectively connect and disconnect such mechanisms.

The phonograph mechanism comprises a mandrel 5 for carryingthe record orrecord. blank 6 and the usual carrier arm (not shown) on which-therecorder 7 and repro-. ducer 8 are so mounted that either is adaptedtobe brought into operative position with respect. to the mandreland therecord or the starting of thev blank carried thereby. Referencecharacter 9 represents a sound onveyer, the inner end of which is,adapted to be slipped. over the.

suitable connecting mechanism 12 betweenthe bell crank lever and thepneumatic device. The pneumatic device consists of a pump 13. mounted onthe frame of the plionogra'ph, another pump 14, and a flexible tube 15connecting these pumps.

of pump 13 is suitably connected to mechanism 12, and is movable toactuate this mechanism, and thereby bell crank lever 11 and'clutchmember4:, by changes of pressure in the column ofair in the tube 15. The

pump 14: comprises a hollow cylindrical casing 17 and a piston v20disposed in the latter; the casing being provided at one end with anipple 18 for connection with thetube 15 and at its other end with aremovable'cap 19, and the piston being secured to arod 21 which extendsthrough the cap 19 and has a button 22' on its outer end. A spiralspring 23, disposed betweenv the end of' casing 17' connected with tube15, or the inner end thereof, and the piston 20, constantly tendsto-force the latter toward the opposite or outer end of this casing. Theouter end portion of rod 21 is reduced to form a shoulder 26 whichcooperates with cap 19 to limit the outwardmovement of the piston 20. rV V A bracket 24 is suitably secured at its ends tothe pump casing 17the major portion of this-bracket being spaced from the'casingandhaving'securedthereto a pair of spring clips 25 which are sprung overthe rigid outer end portion of the sound" conveyer 9, whereby the pump14 will be secured to the sound conveyer in spaced relation thereto andserve-as a handle therefor; The construction and. size of the pumpl lare such as to enable the operator to readily grasp thesame in his handand at the same time permit him to actuate thebutton 22 by" his thumb,as clearly shown in Fig. 1.

It will be obvious that on applying sufii-' cient pressure to the button22 to depress rod 21, piston 20 will be forced inwardly against theaction of spring 23 and, by

means of the column of air in tube 15, the pump 13, connecting mechanism12, and bell crank lever 11, the clutch member 4; will be shifted tooperatively' connect the phono- The sound conveyer is flexible for:

The piston 16 graph mechanism 2 with the driving mechanism 3; and thatwhen this pressure is re-. moved and spring23 is free to .act, thepiston 20 will be forced outwardly, in casing. 17"and the; clutch memberat will be shifted" in the opposite direction to disconnect thephonographand driving mechanisms 2 and 3,

In the absence of means other than that referred to in theabove detaileddescription, it is evident that it will be necessary for the operator tokeep the rod 21 depressedagainst the action of spring 28, bymaintaining'pressure on button 22, as long as it isdesired to keep thephonograph mechanism operating. In order to obviate this necessity, Ihave provided the pump l t with means for automatically holding orlocking the rod 21 in,

depressed position, to thereby prevent the disconnection of the drivingand phonograph mechanisms, until such means'is op-" erated toT6l6lS6.tl11S- rod; This locking means preferably comprises asmallresilient rod27 secured at oneend to the piston or plunger 20and-extending outwardly through aslot 28 inthe cap 19; The outer endportion of! rod 27 is disposed loosely-in a small notch 29'formed in theouter portion of but- 7 ton 22. The rod 27 is cut away or notched nearits outer'end and on the side thereof adjacent rod 21, as indicated at30, whereby the same is provided with a shoulder 31. At its outer endthe rod 27 is provided with a small curved portion or lug 32 whichprojects slightly above the button 22 and extends outwardly from thecenter of the latter. In order that rod 27- maybe readily flexed by aslight outwaidpressure on its upper end, the rod is formed withare'duced portion 33. 1 r

Rod 27, under its own-resiliency, normally tends to assume a positionsubstantially parall'el to the piston rod 21 and inengagement withthe-inner wall of the slot 29 inbutton 22; 'IVhen the parts of the pump14 are in position for effecting the stopping of thephonographmechanism, however, theinner wall o'f slot' 28 in cap 19 bears againstrod 27- and flexes or bends the same away from rod 21, as clearly shownin Fig. 2. 'Upon push ing rod 21 inwardly, as'by applying pressure tobutton 22 by the thumb, to thereby effect the starting of? thephonograph mechanism, the rod 27, after the shoulder 31.

thereof moves past cap 19, will spring in-' wardly' toward rod 21 andits shoulder will engage the inner side of cap 19 to lock the parts ofthe pump in positionfor maintaining the phonograph mechanism'in opera-'tion, as shown in Fig. 3; In order to release rod 21 and piston 20 tothereby efiect the stopping of'the phonograph mechanism, it is merelynecessary to apply sufiicient out:- ward pressure to rod 27 to disengagethe shoulder 31 thereof from cap 19; This may: be readily accomplishedby pressingthe thumb outwardly against or over the lug or outer curvedend 32 of this rod.

Vhile I have specifically described the preferred embodiment of myinvention, it is to be understood that I am not limited to suchembodiment, but that the same is subject to many changes andmodifications in the form, size, and arrangement of parts withoutdeparting from the spirit of the invention. It is obvious, for example,that my invention is not limited to a pneumatic controlling device.
